I have a 41 G506 4x4 Dump, with a 235 and 4 speed. I must admit I am unsure of what the stock trans is (sm420 I think) Maybe some one could fill me in on that. I am looking to put a SB350 in it. My issue is the trans. The current trans has the PTO on the side that I need for the dump bed.

So I guess my questions are:
1. Is it possilbe to use the stock trans?
2. Would I be better off using a SM465?
3. If I were to use the sm465, will the PTO side mount from the old trans bolt to the 465?
4. What modifications to the clutch linkage will be necessary if I went with the sm465?

Thanks inadvance for the info!
